SPECIFICATION forming part of Letters Patent No. 456,413, dated July 21,1891. Application filed March 27, 1891- Serial No. 386,613. (No model.)

To (0% whom it may concern:

Be it known that we, JOHN J. IIEYs, a citizen of Great Britain, and aresident of Lynn, in the county of Essex and State of Massachusetts, andMAURICE V. BRESNAHAN, a citizen of the United States, and a resident ofLynn, in the county of Essex and State of Massachusetts, have jointlyinvented new and useful Improvements in Sole Shaping or LevelingMachines for Boots and Shoes, of which the following, taken inconnection with the accompanying drawings, is a specification.

This invention relates to improvements in sole shaping or levelingmachines for boots and shoes, and it is carried out as follows,reference being had to the accompanying drawings, wherein Figure 1represents a front elevation of the machine, parts of which are shown insection. Fig. 2 is a rear elevation, and Fig. 3 a side elevation, asseen froniX in Fig. 1. Fig. 4 represents a vertical section on the lineY Y, shown in Fig. 1. Fig. 5 represents atop plan View of the machine.Fig. 6 represents a detail vertical section of the last holding device;and Fig. 7 represents a vertical section on the line Z Z, shown in Fig.6. Fig. 8 represents a detail perspective View of the toggle-jointtripping mechanism for carrying the last toward the operator and lookingit in said position after the shoe-sole has been leveled. Fig. 9represents a detail perspective view of the tripping device for startingand stopping the machine; and Fig. 10 represents a sectional frontelevation, and Fig. 11 a side elevation, of said tripping device. Fig.12 rep resents a detail perspective view of the center gnide-braoket forthe last-block, and Fig. 13 represents a detail front view of thetripper-rod adjustment for the toggles.

Similar letters refer to similar parts wherever they occur on thedifferents parts of the drawings.

A A represent the upright frames or sides of the machine, which arefirmly secured together at a proper distance apart, as is usual inmachines of this kind.

B B are vertical rods or posts secured in a suitable manner to theframes A A, and B is a similar post arranged midway between the posts Bb, as shown in Figs. 1, 2, 3, 4, and 5, said posts being preferably seenred in their lower ends to a cross-bar C, attached to the frames A A, asshown in Figs. 1 and 2.

D is the head of the machine, which is verticall y adjustable upon therods B B B, prefcrabl y by means of ad j usting-n uts b b b, as iscommon in this kind and similar machines.

The improved machine is preferably made duplex in constrnction-that is,it is provided with a pair of shoe-holding and pressure de vicesconnected for operation, so as to enable the operator to remove aleveled shoe from one of the lasts and replace it with another while theleveling is done on the other last, and so alternately during therunning of the machine.

E is the driving-shaft, located in hearings in the frames A A and havingsecured to it a pinion e, the teeth of which mesh into the teeth of thegear f, secured to the crank-shaft F, which is journaled in hearings inthe frames A A and provided with diametricallyarranged cranks F F, asshown in Fig. 2. To each crank is pivoted a link G, the lower end ofwhich is pivoted to an actuating bar or rod 71., connected with thelower toggle-lever H, as shown in Figs. 2, 3, 4, and S. The saidtoggle-lever II is pivoted at its lower end at II to the cross-bar C andhas its upper end pivoted at h to the upper toggle-lever I, as shown inFigs. 1, 4, (3, and 8.

K is the last-block, which is pivoted to the upper end of thetoggle-lever I by means of the horizontal pin or bolt 2', the projectingends of which are provided with anti-friction rollers or collars i" 2',(shown in detail in Fig. 7,) the purpose of which will hereinafter bedescribed. The last-block is thus freelyad justable with a rockingmotion on the pin 1, so as to permit the shoe-carrying last to adjustitself automatically relative to the shaping plate or form during theleveling opera tion.

I is a forcingspring arranged between the under side of the last-block Kand upper portion of the toggle-lever I, which serves to normally tipthe said last-block slightly forward,"

as shown in Fig. 6, when the pressure is taken off the shoe-sole, suchforward tipping motion being limited by a projection 7c on the underside of the last-block coming in contact with the forward upper edge ofthe togglelever I, as shown in said Fig. 6.

On the under side of the last-block K is a cam projection which comes incontact with a roller or projection Z on the middle brace L when thelast-block approaches its highest position, by which said last-block isautomatically swunginto alevel (or nearly so) working position, as shownin Fig. 4.

The brace L is composed of a metallic bar extending from one side of theframe A to the other, as in dotted lines, Fig. 2. To automatically guidethe last-block K toward the soleformer D as the upper ends of thetogglelevers I rise, Iprovide the posts B Bwith guides Ii, Figs. 1, 2,and 12. These guides comprise vertical grooves or forks, Fig. 12, to

receive and guide the lateral guide pieces or rollers i on thelast-block K as the toggle-levers I approach the highest position justprevious to the shaping or leveling of the shoesole.

M is the last supported on the last-block and having, preferably, arecess m on its under side adapted to receive a pin 7e", secured to thelast-block K, as shown in Fig. 6. The last is prevented from turningaround the pin k and locked to the last-block by means of a handleM',-having a rod M", adapted to slide forward and backin a recess in thelast-block, and having a projection or pin M adapted to enter a recessin the last M, all as shown in Figs. (Sand 7. After the last has beenthus secured to the last-block the rod M" is secured in place,preferably, by means of a set-screw 70 or equivalent device.

N in Fig. 6 is the shoe placed on the last, and n is its sole, as usual.

D is a vertically-yielding yoke adapted to yield slightly in a recess onthe under side of the head D, as shown in Fig. 1, said yoke having anupwardly-projecting spindle D, passing loosely through a perforation inthe upper end of the head D, and is there provided with an adjusting-nut D In a recess in the head D is located the coiledforcing-spring D surrounding the bolt D between the upper end of. theyoke D and the upper end of the recess in the said head D, as shown inFig. 1,

by which a yielding resistance is obtain ed in shaping the soles. Theyoke D carries a nut D provided with a regulating-screw D, by which thecarriage D is adjusted accord ing to the pressure desired in shaping theshoe-sole.

D is the sole-former, secured to the carriage D in any suitable manner.

D is a plate guided on the posts 13 B B and connected loosely to thecarriage D in any suitable manner, as shown in Fig. 1.

, A is the front brace, secured in any suitable manner to the front ofthe framesAA, which brace serves as a rest against which the uppertoggle-leverIisheld by automatic locking mechanism, hereinafter to bedescribed, when the said toggle-lever and its shoe-holding device areswung forward after the sole of the shoe held on it has been shaped orleveled, so

as to permit such shoe to be removed and replaced by another. Theautomatic locking mechanism above mentioned is constructed as follows:To each link G is pivoted about midway on it an arm or rod 0, having acam projection 0 on its upper side, as shown in Figs. 3, 4, and 8. Theforward end of said rod 0 rests loosely on a block H, Figs. 4 and 13,which is adjustably secured to the lower toggle-lever H and capable of alongitudinal adjustment thereon, so as to raise or lower the forward endof the rod 0, and thereby to adjust the position of its cam projection 0relative to the toggle-tripper I", on which it acts. The said toggletripper I is pivoted at 1 Figs. 4 and 8, to the lower end of thetoggle-lever I and is free to swing on its pivot in the direction of thearrow shown in Figs. 4 and 8, but is limited in its motion in theopposite direction by a lip or projection I coming in contact with thatpart of the toggle-lever I on which it is hung. The said toggle-tripperI is preferably provided with an anti-friction roller 1 in its lowerend, and is also preferably held in its normal position by the influenceof a yielding spring I, as shown in the right-hand portion of Fig. 4.The operation of the said toggle-tripper is as follows: As thetoggle-levers H I are moved by the crank-shaft F and link G from thevertical to their forward positions, the lower end of the tripper 1"comes in contact with the cam projection 0 and tends to swing the uppertoggle-lever I in the direction of arrow shown upon it in Fig. 4, and asthe lower toggle-lever H is swung forward to the extent of its strokethe upper toggle-lever I is brought against the front brace A andtemporarily held locked against it by the tripper I resting on thehighest portion of the cam projection 0, as shown in the left-handportion of Fig. at. As the toggle-levers H I are moved from theirforward to their vertical position the tripper I" is released from thecam projection o and automatically swung by the influence of the springI to the position shown in the right-hand portion of Fig. 4, and so on.

For the purpose of preventing jarring of the toggle-levers H I as theyare being moved from their forward to their central position, and viceversa, we connect said levers frictionally together at their jointedportion, as follows: To one or both sides of one of the toggle-levers weattach brackets P P and on the other toggle-lever we make segmentalfriction-surfaces P P, as shown in Fig. 8. P is a piece of leather orequivalent material preferably attached to an adjustable friction-blockon the inside of the bracket P, and P is a set-screw going through thebracket P, by means of which the friction between the surfaces P and P"is adjusted and the wear on said surfaces taken up from time to time, asmay be required. The toggle-lever I is moved from itsforward to itscentral position by means of a projection or pin and roll 9 on theupperend of the link G acting on the hooked rear end of an actuating barfriction-clutch, as follows:

Q is the treadle, preferably secured to a --rod Q, located in bearingsin the frames A A. Said treadle is normally held upward by the agency ofa suitable spring Q or equivalent device. On the treadle-rod Q ispreferably secured a lever Q carrying a spreaderdisk Q, as shown inFigs. 2 and 5. On the driving-shaft E is loosely journaled thebeltpulley E, Fig. 1, to which a constant rotary motion is imparted bymeans of suitable beltpower. Inside of said loose pulley is splined onthe shaft E the conical friction-clutch disk J", and to the shaft E issecured a collar E between which and the hub of the clutch E" thespreader-roller Q is forced by the depression of the treadle Q, causingthe pulley E, friction-clutch E", and the driving-shaft to befrictionally connected as long as the treadle is depressed, during whichtime the rotary motion from the pulley E is communicated to thedriving-shaft E. We desire to state, however, that any other well-knownfrictionclutch device may be used for imparting a rotary motion to thedriving-shaft from the loosely-rotating belt-pulley without departingfrom the essence of our invention, and we have only represented thefriction-clutch device above mentioned for the purpose of making clearthe operation of the machine.

E, Fig. 9, is a brake-wheel secured to the driving-shaft E, againstwhich is brought the brake-shoe Q on the treadl Q (shown in dotted linesin Fig. 9) when the treadle is released, so as to stop the driving-shaftfrom rotating as soon as the friction-clutch is released. In connectionwith this our duplex shaping or leveling machine we use an automaticstopping mechanism for automatically stopping the machine as soon as thedriving-shaft has completed one-half of its revolution, at

which time one of the shoes is being shaped or leveled and the other oneheld forward toward the operator to enable him to'remove it and replaceit with another one to be shaped or leveled before starting the machineby the depression of the treadle. This automatic stopping mechanism isconstructed as follows: To one of the bearings A, Figs. 9 and 10, inwhich the crank shaft F is journaled, or to any stationary part of themachine, is pivoted a dog Q, to which is pivoted a link Q, the lower endof which is pivoted to the treadle Q.

Q is a spring connected in one end to the link Q and in the otherend tothe treadle Q, as shown inFig. 9.

Onthe shaft F are two diametrically-arranged projections F F. (Shown inFigs. 9 and 10.) a

The operation of the said automatic stopping mechanism is as follows:Vhen the treadle Q is depressed for starting the drivingshaft, the linkQ is drawn forward by the action of the spring Q until the three fulcraon which the said link and the dog Q are hung come in a line with eachother, causing the treadle to be held depressed against the influence ofits spring Q" until one of the projections F" on the crank-shaft F comesin contact with the upper end of the dog Q, causing it to be tripped, asshown in Fig. 9, thereby liberating the treadle Q and causing it to beraised by the influence of its spring Q at the same time that thefriction-clutch E is liberated from the rotary pulleyE and thebrake-shoe Q brought against the pulley E on the driving-shaft E, thusautomatically stopping the machine at the desired position. The machineremains stationary until the treadle is again depressed by the operator,causing the crank-shaft to rotate one-half of a revolution, and then tobe automatically stopped, and so on during the operation of the machine.

In machines of this kind it is desirable that a means should beestablished for stopping the machine at any time in case of accidents orbreakage or in trying the pressure on a change in lasts or forms, andfor this purpose we use a rod R, having its rear end connected to thelink Q and having its forward end suitably guided at thefront of themachine and having preferably a handle or knob r for its operation, asshown in Figs. 3 and 9. Thus it will be seen that the machine may bestopped at any time at the will of the operator simply by pushing backthe rod R, causing the dog Q to be tripped, the treadle to be raised,the friction to be taken off the pulley E, and the brake-shoe Q put onthe pulley E r The rod B may be locked into position for holding themachine stopped by means of a suitable latch '2'. (Shown in Figs. 1 and3.)

The operation of the machine is as follows: Before the machine isstarted the operator puts a shoe on the last, which is for the timebeing held forward in a locked position, a shoe being in the meantimeheld upon the other last, which is forced upward against the overheadformer while the sole on said shoe is being shaped or leveled. Theoperator now depresses the tr'eadle, causing the friction to be put on,by which the machine is started and the treadle' automatically retainedin its starting position. During onehalf of a revolution of thecrank-shaft the upper toggle-lever, upon the last-block of which theoperator has placed a shoe, is released from its tripper and frontbrace, drawn backward by the hooked rod and projection, as described,and guided between the grooves on the center brace and caused toriseupward, carrying the shoe-sole on its last against thespring-pressed former and keeping it .under pressure after the machineis stopped until the treadle is again depressed, said treadle havingautomatically been released and the machine stopped at the completion ofhalf TIO a revolution of the crank-shaft. The lastblock being pivoted tothe toggle-lever will automatically adjust itself against the soleformerat or about the time it is brought against it. Vhile this takes placethe togglelever and last which were under pressure have beenautomatically moved forward and locked in a forward position to enablethe operator to remove the leveled shoe and replace it with another, andso on during the operation of the machine.

By having the upper toggle-lever audits last movable to and from theoperator great facility is obtained in placing the shoes in position andremoving them, and liability to accidents caused by the operators handsbeing jammed, pressed, or otherwise injured is obviated.

Having thus fully described the nature, construction, and operation ofour invention, we wish to secure by Letters Patent and claim- 1. In asole shaping or leveling machine,.the
